As soon as the sheet is free of the impression-cylinder,and hence wholly supported by the carrier, the several endless tapesthereof are caused to rotate in a direction the reverse of the bodilymovement of the carrier itself, with the result that the carrier willmove out from beneath the sheet of paper and allow the latter to droponto table 7. This rotation of t-he endless tapes is accomplished by aring or peripheral enlargement 17 on the end of the rearmost cross-rodof the carrier engaging the under side of a contact-plate 18,overhanging one of the carrier-chains. This plate is adjustably securedto frame l by nutted bolts 19, passed through longitudinal slots 20 of a.second overhanging plate 2l, secured to such frame. 22 designatestracks for supporting the chains as they travel horizontally. Byadjusting the contact-plate 18 longitudinally the point at which theendless tapes are caused to travel reversely may be regulated to suitstock of different sizes-that is to say, for large stock the engagementof the crossrod with the contact-plate will be postponed, while forsmall stock the engagement will occur soon after such cross-rod beginsits forward horizontal movement.

On the delivery table 7 are adjustably mounted inner and outer gages 23and a side gage 24. A second side gage 25 is in the form of a bar hingedto a horizontal bar 26, adjustable transversely of the table, thegagebar being held normally vertically or in its uprightposition by aspring 27. Adjacent to this side gage 25 table 7 has a groove or cut-out28 sufficiently wide to admit the hand of a person to grasp the pile ofstock located on the table and to pull the same outwardly to one side,the side gage 25 thereupon being moved downwardly into the groovewherein its adjusting-bar 26 is located. As the stock is thus moved toone side and is free of the side gage the latter will immediately returnto its normal position under the action of its spring. By this means itwill be noted that the gages retain the stock in proper position as itis piled on the table, and yet permit of its ready removal at any time.The hand cut-out is extended inwardly from one side of the table to andterminates within the field occupied by the stock deposited thereon,which stock extends over such cut-out to allow of its being easilygrasped.

From what has been said it will be noted that I have provided meanswhereby stock discharged from a rapidly-operating printing-press may bequickly and evenly piled on a delivery-table, that its delivery onto thetable is effected in a single handling of a sheet or other stock andbefore the carrier completes the forward movement over the table, andthat the point of discharge of the stock from the carrier is controlledby the adjustment of the contact-plate, which gives to the carrier-tapesa travel in a direction the reverse of the bodily movement of thecarrier. It will also be observed that the stock may be readilyWithdrawn from the table at any time without interfering with theoperation of the carriers.

I claim as my inventionl. The combination Wit-h a printing or othermachine, of a delivery-table, a carrier movable horizontally over suchtable and designed to loosely support a sheet during itsmovement awayfrom the machine, and means for automatically arresting the travel ofthe sheet with the carrier before the latter reaches the limit of itstravel over the table for effecting the immediate discharge of the sheetdirect onto the table, as set forth.
